True
O False

True

Explanation:

Conglomerates are clastic sedimentary rock that contains mostly pebble-size rounded clasts. The spaces between the clasts are generally filled with smaller particles and/or chemical cement that then binds and formed the rock matrices together.

Sedimentary breccia is a type of clastic sedimentary rock which is made of angular to subangular, randomly oriented clasts of other sedimentary rocks. A conglomerate, by contrast, is a sedimentary rock composed of rounded fragments or clasts of pre-existing rocks.
